Input unit 11 includes, for example, a keyboard and a mouse, and receives an input operation from user P. Display 13 includes, for example, an LCD (Liquid Crystal Display) and is caused by control of controller 12 to display text or images on the screen.

The data transmitter 14 is controlled by the controller 12 to send printer 2 data received from the storage 16. Data receiver 15 receives the data transmitted from printer 2. The storage 16 is configured of, for example, a memory such as a RAM (Random Access Memory) and an HD (Hard Disc) and includes OS (Operating System Software) 31, application (software) 32, printer driver (software) 33, print setting 34, and charge setting 35.

OS 31 is software which is executed by controller 12 to provide input/output functions such as data input from input unit 11 or screen output to display 13 and basic functions to be commonly used by application 32, such as management of storage 16, and manages entire computer 1. Application 32 is software which is managed by OS 31. Also, OS 31 and application 32 include a function to instruct printer driver 33 to print data inputted by user P via input unit 11 with an input of a print command by pressing down a “print” button or the like which is displayed on display 13 with an operation of input unit 11 by user P.

Printer driver 33 is a program to convert document data created in application 32 into data in a format capable of being interpreted by printer 2, and is a program to provide user P with a GUI (Graphical User Interface) as a screen for setting the functions of printer 2 or printer driver 33 before printing. Print setting 34 as print setting information is for storing, for example, an enlargement/reduction rate, which is an enlargement rate or a reduction rate, a document paper size and a printing paper size as setting values.

Charge setting 35 as charge setting information is a copy of charge setting 28 stored in storage 27 of printer 2 to be described later and has the same configuration as that of charge setting 28. Printer 2 includes data receiver 21, data transmitter 22, controller 23, input unit 24, display 25, printer 26, storage 27, and paper storage 29. Controller 23 is configured of, for example, a CPU to control an entire operation of printer 2 by controlling data receiver 21, data transmitter 22, input unit 24, display 25, printer 26, and paper storage 29 based on various programs and data which are stored in storage 27.

Storage 27 is configured of a RAM or HD which stores print setting information, print data, charge setting 28, or the like, and a ROM (Read Only Memory) which stores firmware, character font data, or the like as various programs for controlling printer 2. Input unit 24 includes an operation button disposed on an operation panel, for example, to receive an input operation made by user P. Display 25 includes, for example, an LCD and is caused by control of controller 23 to display text or images on the screen.

The data transmitter 22 is controlled by the controller 23 to transmit data to computer 1. The data receiver 21 receives the data transmitted from the computer 1. Printer 26 is a print mechanism to print data onto printing paper. Paper storage 29 includes, for example, tray A41, tray B42, tray C43, tray D44, and tray E45, so to be capable of respectively storing different sizes or kinds of printing media in the trays and supplying printer 26 with the printing media.

As illustrated in FIG. 7, charge setting 28 as a charge setting list is configured of paper sizes which are stored in the trays A41 to E45 of paper storage 29 as paper storage trays, color unit prices as color print unit price information for color printing on each paper size, and monochrome unit price as monochrome print price information for monochrome printing on each paper size. Note that charge setting 35 of computer 1 is a copy of charge setting 28.

Hereinafter, the configuration of printer driver 33 which is stored in storage 16 of computer 1 is described by referring to FIG. 1 based on the block diagram illustrating the configuration of printer driver in the first embodiment. In FIG. 2, printer driver 33 has print setting change program 101 and print data creation program 102.

Print setting change program 101 as an enlargement/reduction rate designation unit is an enlargement/reduction rate designation program to designate an enlargement/reduction rate, a document paper size, and a printing paper size to be used to create print data. Print setting change program 101 includes a function to provide user P with a GUI for setting before printing the functions of printer 2 and printer driver 33 among the functions of printer driver 33. Print setting change program 101 acquires settings from print setting 34 to be reflected on the GUI when GUI is displayed and saves the settings on the GUI in print setting 34 when the GUI is ended.

Print data creation program 102 includes a function to convert document data created in application 32 into print data in a data format capable of being interpreted in printer 2 among the functions of printer driver 33. The print data created in this print data creation program 102 is created based on the print setting information stored in print setting 34. Print data creation program 102 has charge setting acquisition program 103, enlargement/reduction mode list-up program 104, fee calculation program 105, enlargement/reduction mode display program 106, page data creation program 107, and print data transmission program 108.

Charge setting acquisition program. 103 as an information acquisition unit is an information acquisition program to acquire size information and unit price information of the printing media to be stored in printer 2, and acquires charge setting 28 from printer 2. Enlargement/reduction mode list-up program 104 as an output mode extraction unit is an output mode extraction program to extract output modes based on the enlargement/reduction rate designated in print setting change program 101, and the size information of the printing media acquired in charge setting acquisition program 103. The enlargement/reduction mode list-up program 104 lists up the enlargement/reduction modes from the enlargement/reduction rate stored in print setting 34, the paper size, and charge setting 35.

Fee calculation program 105 as a fee calculation unit is a fee calculation program to calculate a fee for each output mode extracted in the enlargement/reduction mode list-up program 104 in such a manner that the number of printing media to be used is calculated from the size information of the printing media acquired in the charge setting acquisition program 103. Then a fee is calculated from the number of printing media and unit price information acquired in charge setting acquisition program 103. Then the calculation program 105 calculates a fee based on charge setting 35 for the enlargement/reduction mode listed up by enlargement/reduction mode list-up program 104. Also, fee calculation program 105 calculates a fee by determining whether or not the printing data is color or monochrome.

Enlargement/reduction mode display program 106 as an output mode display unit displays each fee calculated in fee calculation program 105 together with the output mode to accept a selection of the output mode. Enlargement/reduction mode display program 106 then displays on display 13 each enlargement/reduction mode listed up by enlargement/reduction mode list-up program 104, and the fee of each enlargement/reduction mode calculated in fee calculation program 105 to allow user P to select the enlargement/reduction mode through input unit 11.

Page data creation program 107 as a print data creation unit is a print data creation program to create print data based on the output mode selected by enlargement/reduction mode display program 106, and creates page data from the document data as print data in a data format capable of being interpreted in printer 2 based on print setting 34 and the enlargement/reduction mode selected by enlargement/reduction mode display program 106. Print data transmission program 108 is a program to transmit page data created in page data creation program 107 to printer 2 via data transmitter 14.

Effects of the above-described configuration are described. Firstly, printing processing to be performed by the image processing system is briefly described by referring to FIGS. 1 and 2 according to steps expressed by S in the drawings of the flowchart illustrating the flow of the printing processing in the first embodiment in FIG. 8.

S101: print setting change program 101 in printer driver 33 of computer 1 performs print setting change processing to change print setting 34 in storage 16 based on the print setting information inputted in input unit 11 through the operation of user P. Print setting 34 is referred to when the document data created by application 32 operating on OS 31 is converted to print data.

S102: Application 32 accepts the operation of user P for instructing the printing with input unit 11 and starts the printing.

S103: Print data creation program 102 in printer driver 33 performs print data creation processing to create the print data.

S104: Data transmitter 14 in computer 1 transmits the created print data to printer 2 and data receiver 21 of printer 2 receives the print data.

S105: Print unit 26 of printer 2 prints the print data received by data receiver 21. At this time, print unit 26 performs a printing after feeding the designated printing medium from paper storage 29 and charges based on charge setting 28 stored in storage 27. Then the present processing is terminated.

Next, print setting change processing to be performed by the print setting change program of the printer driver of the computer is described by referring to FIGS. 1 and 2 according to steps expressed by S in the drawings of the flowchart illustrating the flow of the print setting change processing in the first embodiment in FIG. 9. Note that this print setting change processing is processing to be performed at S101 of FIG. 8.

S201: Print setting change program 101 acquires print setting 34 including a document paper size, a printing paper size, and an enlargement/reduction rate from storage 16.

S202: Print setting change program 101 sets the acquired print setting as setting parameters for each item. For example, print setting change program 101 sets “A4” as a setting parameter of the document paper size, and also sets “A4” as a setting parameter of the printing paper size, and sets “100%” as the setting parameter of the enlargement/reduction rate.

S203: Print setting change program 101 displays GUI in which the setting parameter set at S202 is reflected on display 13.

S204: Print setting change program 101 accepts the operation of changing the settings of the items, which is made by user P through input unit 11, and changes the settings of the items. For example, when the print data illustrated in FIG. 3 is printed, the document size is “A4” and thus the setting parameter of the document paper size is kept as “A4.” Then, since the enlargement/reduction rate is 141%, print setting change program 101 changes the setting parameter of the printing paper size from “A4” to “A3,” and the enlargement/reduction rate from “100%” to “141%.” S205: Print setting change program 101 displays the termination of the print setting on the GUI, and determines whether or not an “OK” button is pressed down on the GUI. When it is determined that the button is pressed, the processing proceeds to S206. When it is determined that a “Cancel” button other than the “OK” button is pressed down, the processing terminates without saving the changed setting in print setting 34.

S206: Print setting change program 101 terminates the present processing after saving the changed setting in print setting 34.

Next, print data creation processing to be performed by the print data creation program of the printer driver of the computer is described by referring to FIGS. 1 and 2 according to steps expressed by S in the drawings of the flowchart illustrating the flow of the print data creation processing in the first embodiment in FIG. 10. Note that this print setting change processing is performed at S103 of FIG. 8.

S301: Print data creation program 102 acquires paper size names, widths, and heights of the document paper size and printing paper size, and enlargement/reduction rates R (%) from print setting 34.

S302: Print data creation program 102 determines whether or not the acquired enlargement/reduction rate R is 100%. When it is determined that the rate is 100%, enlargement/reduction is not performed, and thus the processing proceeds to S315 to create page data having the designated setting. When it is determined that the rate is not 100%, the processing proceeds to S303.

S303: When print data creation program 102 determines that the acquired enlargement/reduction rate R is not 100%, charge setting acquisition program 103 acquires charge setting 28 from printer 2.

At this time, charge setting acquisition program 103 creates command data as a command to acquire the charge setting and transmits the created data from data transmitter 14 to the data receiver 21 of the printer 2. Controller 23 of printer 2 executes the command received by data receiver 21 and transmits charge setting 28 stored in storage 27 from data transmitter 22 to data receiver 15 of computer 1.

S304: Charge setting acquisition program 103 proceeds the processing to S305 when it is determined that charge setting 28 has been successfully acquired. On the other hand, when charge setting 28 does not exist in printer 2, controller 23 of printer 2 cannot correctly execute the command due to the absence of a transmission target. Thus, charge setting acquisition program 103 determines that the acquisition of charge setting 28 has failed. Thus, the processing proceeds to S315 to create page data having the designated setting because information required for the subsequent processing does not exist.

S305: Charge setting acquisition program 103, having successfully acquired charge setting 28, saves charge setting 28 transmitted to data receiver 15 in the storage 16, as charge setting 35.

S306: Charge setting acquisition program 103 acquires I which is the number of items of charge setting 35. As illustrated in FIG. 7, charge setting 35 is configured of paper sizes which are stored in the trays A41 to E45 of paper storage 29 as paper storage trays, a color unit price as a color print unit price when color printing is made on each paper size, and a monochrome print unit price when monochrome printing is made on each paper size. Thus, the number I of the items can be acquired from the configuration. In the example illustrated in FIG. 7, the number I of the items is 5.

S307: Charge setting acquisition program 103 checks a spool state of the print data. Here, the print data is spooled on a spooler in, for example, an EMF format (Enhanced Metafile Format) before the page data creation processing is performed in print data creation program 102 of printer driver 33. In general, the spooled print data is subsequently subjected to the page data creation processing by print data creation program 102 of printer driver 33. However, it is assumed here that the print data is not delivered to page data creation program 107 before the enlargement/reduction mode setting screen is terminated.

S308: Charge setting acquisition program 103 proceeds the processing to S307 until the spool state of the print data is changed from the spooling state to the end of the spooling. When the spool state is ended, the processing proceeds to S309.

S309: Charge setting acquisition program 103 detects the end of the spooling and acquires the total number N of pages of the print data from the spooled print data.

S310: Next, enlargement/reduction mode list-up program 104 creates an enlargement/reduction mode list. Note that the process of creating the enlargement/reduction mode list is described later.

S311: Next, fee calculation program 105 calculates a fee for each item of the created enlargement/reduction mode list. Note that the processing of calculating the fee for each item of the enlargement/reduction mode list is described later.

S312: Next, enlargement/reduction mode display program 106 displays an enlargement/reduction mode setting screen.

Here, the enlargement/reduction mode setting screen for printing one page of A4 enlarged by 141% on A3 paper, like the print data illustrated in FIG. 3, is enlargement/reduction mode setting screen 120 illustrated in FIG. 4. This enlargement/reduction mode setting screen 120 displays list 121 of four print mode candidates in the center and displays preview 122 with the selected print mode thereunder. Also, enlargement/reduction mode setting screen 120 displays OK button 123 to instruct printing by adopting the enlargement/reduction mode selected by user P, and cancel button 124 to instruct printing with a previously-designated setting without adopting the enlargement/reduction mode selected by user P.

The list of the candidates includes a print mode of enlargement/reduction printing in a paper size designated in advance, a print mode of enlargement/reduction printing in a paper size larger than the designated paper size, a print mode using a poster print function to perform enlargement printing by splitting an enlarged image by multiple sheets, and a print mode using an N-up print function to print multiple reduced pages on one sheet collectively. Those modes are listed up at S310.

The print data illustrated in FIG. 3 includes a color image in the upper half portion of the paper and a monochrome image in the lower half portion of the paper without a color image. Thus, when the print data is printed by splitting it by two A4 pages using the poster print function, the number of printing pages of the color page is one and the number of printing pages of the monochrome page is one. Thus, the fee becomes 25 yen In Japanese currency of this example) which is the minimum value. Also, when four pages of A4 document are reduced by 70% to be printed on A5 paper like the print data illustrated in FIG. 5, enlargement/reduction mode setting screen 130 illustrated in FIG. 6 is displayed. This enlargement/reduction mode setting screen 130 displays a list 131 of four print mode candidates in the center and displays preview 132 with the selected print mode thereunder.

Also, enlargement/reduction mode setting screen 130 displays OK button 133 to instruct printing by adopting the enlargement/reduction mode selected by user P and cancel button 134 to instruct printing with a previously-designated setting without adopting the enlargement/reduction mode selected by user P. When the print data illustrated in FIG. 5 is collectively printed on two sheets of A4 paper using the N-up print function, the number of color pages to be printed is two and the fee of 30 yen is the lowest.

S313: Enlargement/reduction display program 106 accepts an operation of selecting a desired enlargement/reduction mode by user P on the enlargement/reduction mode setting screen.

S314: Enlargement/reduction mode display program 106 accepts an operation of terminating the enlargement/reduction mode setting screen by user P on the enlargement/reduction mode setting screen. When OK button 123 illustrated in FIG. 4 is pressed down, the selected enlargement/reduction mode is adopted for the page data creation processing. When cancel button 124 is pressed down, the selected enlargement/reduction mode is not adopted for the page data creation processing but instead, the enlargement/reduction mode designated in advance is adopted for the page data creation processing. At that time, enlargement/reduction mode display program 106 starts supplying the print data spooled in the spooler with page data creation program 107.

S315: Page data creation program 107 adopts the selected or designated enlargement/reduction mode to create page data. Then, the processing is terminated.

Hereinafter, the enlargement/reduction mode list creation processing which is performed by the enlargement/reduction mode list-up program is described by referring to FIGS. 11 to 14. Note that this enlargement/reduction mode list creation processing is performed at S310 of FIG. 10.

Firstly, enlargement/reduction mode list creation processing is briefly described by referring to FIGS. 1 and 2 according to steps expressed by S in the drawings of the flowchart illustrating the flow of the enlargement/reduction mode list creation processing in the first embodiment in FIG. 11.

S401: Enlargement/reduction mode list-up program 104 initializes the list number T which is a variable expressing the number of lists with “0.”

S402: Enlargement/reduction mode list-up program 104 adds the print mode in the designated paper size into the enlargement/reduction mode list.

Here, the enlargement/reduction mode list is a group of items having 10 items as illustrated in FIG. 20 in one item of the list.

The 10 items include: enlargement/reduction mode ID which is identification information for identifying an enlargement/reduction mode; a printing paper size indicating a size of the medium onto which enlarged/reduced page data is to be printed; the number of media to be printed, which is determined by considering the result of the poster print or the N-up print; X which indicates the number of pages split in the lateral direction when the poster print function is used and indicates the number of pages arranged in the lateral direction when the N-up print function is used; Y which indicates the number of pages split in the longitudinal direction when the poster print function is used and indicates the number of pages arranged in the lateral direction when the N-up print function is used; a printing direction which indicates which of the portrait orientation and the landscape orientation of the printing medium is used to arrange the page data; the number of color pages which indicates the number of pages to be printed in color among the total number of pages determined by considering the result of the poster print or the N-up print; the number of monochrome pages which indicates the number of pages to be printed in monochrome among the total number of pages determined by considering the result of the poster print or the N-up print; a fee indicating a fee to be charged for printing by this enlargement/reduction mode; and a minimum-fee flag which is a flag indicating the least expensive enlargement/reduction mode in the enlargement/reduction mode list, for example.

The enlargement/reduction mode as an output mode is an output mode of outputting on a printing medium with a designated size, an output mode of outputting on a printing medium with a size larger than a designated printing medium size, and an output mode of outputting an enlarged image on multiple printing media or an output mode of outputting multiple pages on one printing medium. These modes are identified by enlargement/reduction mode IDs. The enlargement/reduction mode IDs are expressed by numeral values of 1 to 4, for example, as illustrated in FIG. 19. ID1 is an ID indicating the enlargement/reduction print mode on paper with a size designated in advance. ID2 is an ID indicating the enlargement/reduction print mode on paper having a size designated in advance. ID3 is an ID indicating the enlargement/reduction print mode of printing data of one page on multiple printing media using the poster print function. ID4 is an ID indicating the mode of printing the printing data of multiple pages collectively onto one printing medium using the N-up print function.

As for the items to be added at S402, when the print data is the print data illustrated in FIG. 3, as illustrated in No. 1 in FIG. 2, “1” is set for the enlargement/reduction mode ID, “A3” for the printing paper size, “1” for the number of printing pages, “1” for X, “1” for Y, and “longitudinal” for print direction. Since the number of color pages, the number of monochrome pages, the fee and the minimum-fee flag are set at S311, “0” is temporarily set for each of these items. Also, as for the items to be added at S402, when the print data is the print data illustrated in FIG. 5, as illustrated No. 1 in FIG. 2, “1” is set for the enlargement/reduction mode ID, “A5” for the printing paper size, “4” for the number of printing pages, “1” for X, “1” for Y, and “longitudinal” for print direction, and similarly “0” is temporarily set for each of the number of color pages, the number of monochrome pages, the fee and the minimum-fee flag.

S403: Next, enlargement/reduction mode list-up program 104 adds “1” into the listed number.

S404: Enlargement/reduction mode list-up program 104 performs a processing to add the print mode on paper having a size larger than the designated paper size. The processing is described later.

S405: Enlargement/reduction mode list-up program 104 determines whether enlargement printing is performed or reduction printing is performed depending on whether the enlargement/reduction rate R is larger or smaller than 100%. When it is determined that it is an enlargement printing whose enlargement/reduction rate R is larger than 100%, the processing proceeds to S406. When it is determined that it is a reduction printing whose enlargement/reduction rate R is smaller than 100%, the processing proceeds to S407.

S406: When it is determined that it is the enlargement printing whose enlargement/reduction rate R is larger than 100%, enlargement/reduction mode list-up program 104 performs processing to add the enlargement print mode into the enlargement/reduction mode list using the poster print function. The process of adding the enlargement print mode into the enlargement/reduction mode list by using the poster print function is described later.

S407: When it is determined that it is the reduction printing whose enlargement/reduction rate R is smaller than 100%, enlargement/reduction mode list-up program 104 performs processing of adding the reduction print mode into the enlargement/reduction mode list using the N-up print function. The processing of adding the reduction print mode into the enlargement/reduction mode list by using the N-up print function is described later.

Next, the process of adding the print mode on paper having a size larger than the designated paper size, which is performed by the enlargement/reduction list-up program, into the enlargement/reduction mode list is described by referring to FIGS. 1 and 2 according to steps expressed by S in the figures in the flow illustrating the enlargement/reduction mode list creation processing in the first embodiment in FIG. 12. The processing of adding the print mode on paper having a size larger than the designated paper size into the enlargement/reduction mode list is processing which is performed at S404 in FIG. 11. The processing is the process of adding the print mode on the least expensive paper into the enlargement/reduction mode list among the sheets of paper having sizes larger than the designated paper size by using charge setting 35. Charge setting 35 is a charge setting list as illustrated in FIG. 7, and enlargement/reduction mode list-up program 104 performs the processing sequentially with reference to the information of charge setting 35.

S501: Enlargement/reduction mode list-up program 104 initializes variable C expressing the list No. of charge setting 35 with “0.”

S502: Enlargement/reduction mode list-up program 104 initializes a loop counter i with “0.”

S503: Enlargement/reduction mode list-up program 104 initializes a color charging unit price U with “0.” Here, the color charging unit price U is used for determining the relative levels of the charging unit price among the printing media. In the embodiment, the high and low relationship among printing media are common to the monochrome charging unit price and the color charging unit price, and the charging unit price is determined as high or low using the color charging unit price as a representative.

S504: Enlargement/reduction mode list-up program 104 determines whether or not the loop counter i has a value smaller than the total number I of items of the list of charge setting 35. When it is determined that the loop counter i has a value smaller than the total number I of items of the list of charge setting 35, the processing proceeds to S505. When it is determined that the loop counter i has a value equal to or larger than the total number I of items of the list of charge setting 35, the processing proceeds to S512. It is adopted here that when all the items of the list of charge setting 35 are checked, the value of the loop counter i becomes equal to the value of the total number I of items, and the processing proceeds to S512 out of the loop. It is adopted that the value of the loop counter i being smaller than the total number of items means that all the items of the list of charge setting 35 are not checked and the following items are to be checked.

S505: Enlargement/reduction mode list-up program 104 compares a height Ho of the designated printing paper size with a height Hi of a paper size stored as an item of the i-th list. When the height Hi is larger than the height Ho, the processing proceeds to S506. When the height Hi is equal to or smaller than the height Ho, it is determined that the designated printing paper size is smaller than the page size stored in the list and the consideration of a charging unit price is excluded. Then, the processing proceeds to S511.

S506: Enlargement/reduction mode list-up program 104, having determined that the height Hi is higher than the height Ho, compares a width Wo of the designated printing paper size with a width Wi of a paper size stored as an item of the i-th list. When the width Wi is larger than the width Wo, the processing proceeds to S507. When the width Wi is equal to or smaller than the width Wo, it is determined that the designated printing paper size is smaller than the page size stored in the list and the consideration of a charging unit price is excluded. Then, the processing proceeds to S511.

S507: Enlargement/reduction mode list-up program 104, having determined that the width Wi is larger than the width Wo, determines whether or not a color charging unit price U is “0.” When it is determined that the color charging unit price U is “0,” this means that the page size stored in the list is the paper size having an original large size, and the processing proceeds to S509 while skipping a comparison on color charging unit price in S508. When it is determined that the color charging unit price U is not “0,” this means that a large paper size is used as a print target paper size at least once, and the processing proceeds to S508.

S508: Enlargement/reduction mode list-up program 104, having determined that the color charging unit price U is not “0,” compares the color charging unit price U with a color unit price of the list of charge setting 35. When it is determined that the color unit price Ui is equal to or smaller than the color charging unit price U, this means that the paper size is larger than the designated paper size and the color unit price Ui of charge setting 35 is already equal to or smaller than the color charging unit price. Then, the processing proceeds to S509. On the other hand, when it is determined that the color unit price Ui is larger than the color charging unit price U, this means that the paper size is larger than the designated paper size but the color charging unit price U which has been selected is cheaper than the color unit price Ui. Then, the processing proceeds to S511.

S509: Enlargement/reduction mode list-up program 104, having determined that the color unit price Ui is equal to or smaller than the color charging unit price U, substitutes the i-th color unit price Ui of charge setting 35 for the color charging unit price U.

S510: Enlargement/reduction mode list-up program 104 substitutes the loop counter i for variable C indicating the list No. of charge setting 35. Accordingly, the list No. of charge setting 35 which is a selection target is stored as candidate information.

S511: Enlargement/reduction mode list-up program 104 adds “1” to the loop counter i, which is then updated, in order to process the next items of charge setting 35. Then, the processing proceeds to S504.

S512: Enlargement/reduction mode list-up program 104, having determined that the loop counter i has a value equal to or larger than the total number I of items of the list of charge setting 35 at S504, determines whether or not the color charging unit price U is “0.” When it is determined that the color charging unit price U is “0,” this means that the charge setting 35 does not has a paper size larger than the designated paper size. Thus, the processing is terminated without being added into the enlargement/reduction mode list. When it is determined that the color charging unit price U is not “0,” this means that the charge setting 35 had a paper size larger than the designated paper size. Thus, the processing proceeds to S513.

S513: Enlargement/reduction list-up program 104 adds the list No. of charge setting 35, which is a selection target, into the enlargement/reduction mode list by utilizing the stored candidate information.

At this time, enlargement/reduction mode list-up program 104 can see the list No. of charge setting 35 with the value stored in variable C indicating the list No. of charge setting 35.

For example, when the print data (printing paper size A3) illustrated in FIG. 3 is printed, if the selection is made from the charge setting list illustrated in FIG. 7, “2” is stored in variable C, and a candidate to be printed on the paper size A3+ of No. 3 by referring the index starting from 0 is added into the enlargement/reduction mode list. At this time, enlargement/reduction mode list-up program 104 sets “2” for enlargement/reduction mode ID of the enlargement/reduction mode list, “A3+” for the printing paper size, “1” for the number of printing pages, “1” for X, “1” for Y, and “longitudinal” for a paper orientation, and temporarily sets and adds a provisional value of “0” for the number of color pages, the number of monochrome pages, the fee, and the minimum-fee flag.

S514: Enlargement/reduction mode list-up program 104 adds “1” into the number T of the lists. Then, the processing is terminated.

Next, the process of adding the enlargement print mode using the poster print function, which is performed by the enlargement/reduction list-up program, into the enlargement/reduction mode list is described by referring to FIGS. 1 and 2 according to steps expressed by S in the figures in the flow of the enlargement/reduction mode list creation processing in the first embodiment in FIG. 13. The process of adding the enlargement print mode using the poster print function into the enlargement/reduction mode list is performed at S406 in FIG. 11.

The processing is processing of adding the enlargement print mode using the poster print function to print multiple pages on paper having a size smaller than the designated paper size into the enlargement/reduction mode list by using charge setting 35. Charge setting 35 is a charge setting list as illustrated in FIG. 7, and enlargement/reduction mode list-up program 104 performs the processing sequentially referring to the information of charge setting 35.

S601: Enlargement/reduction mode list-up program 104 initializes a loop counter i with “0.”

S602: Enlargement/reduction mode list-up program 104 determines whether or not the loop counter i has a value smaller than the total number I of the items of the list of charge setting 35. When it is determined that the loop counter i has a value smaller than the total number I of items of the list of charge setting 35, it determines that all the items are not checked, and the processing proceeds to S603. When it is determined that the loop counter i has a value equal to or larger than the total number I of items of the list of charge setting 35, it determines that all the items have been checked, and thus the processing is terminated.

S603: Enlargement/reduction mode list-up program 104 calculates how many pages Xp of printing paper having a printing paper size of the i-th list of charge setting 35 are required to exceed a width of a printing paper size designated in advance when the pages Xp are arranged in the lateral direction with their longitudinal directions set in the portrait orientation. Here, the number of pages Xp arranged in the lateral direction can be obtained by dividing a width Wo of the printing paper size designated in advance by a width Wi of the printing paper size of the i-th list of charge setting 35. Note that the number of paper sheets Xp is an integer which is obtained by rounding up after the decimal point.

S604: Enlargement/reduction mode list-up program 104 calculates how many pages Yp of printing paper having the printing paper size of the i-th list of charge setting 35 are required to exceed a height of the printing paper size designated in advance when the pages Yp are arranged in the longitudinal direction with their longitudinal directions set in the portrait orientation. Here, the number of pages Yp arranged in the longitudinal direction can be obtained by dividing a height Ho of the printing paper size designated in advance by a height Hi of the printing paper size of the i-th list of charge setting 35. Note that the number of paper sheets Yp is an integer which is obtained by rounding up after the decimal point.

S605: Enlargement/reduction mode list-up program 104 calculates how many pages Xq of printing paper having the printing paper size of the i-th list of charge setting 35 are required to exceed the width of the printing paper size designated in advance when the pages Xq are arranged in the lateral direction with their longitudinal directions set in the landscape orientation. Here, the number of pages Xq arranged in the lateral direction can be obtained by dividing the width Wo of the printing paper size designated in advance by the height Hi of the printing paper size of the i-th list of charge setting 35. Note that the number of pages Xq is an integer which is obtained by rounding up after the decimal point.

S606: Enlargement/reduction mode list-up program 104 calculates how many pages Yq of printing paper having the printing paper size of the i-th list of charge setting 35 are required to exceed the width of the printing paper size designated in advance when the pages Xq are arranged in the longitudinal direction with their longitudinal directions set in the landscape orientation. Here, the number of pages Yq arranged in the longitudinal direction can be obtained by dividing the height Ho of the printing paper size designated in advance by the width Wi of the printing paper size of the i-th list of charge setting 35. Note that the number of paper sheets Yq is an integer which is obtained by rounding up after the decimal point.

S607: Enlargement/reduction mode list-up program 104 determines whether or not a product of the number of pages Xp calculated at S603 and the number of pages Yp calculated at S604 is larger than 1 in order to determine whether or not the printing paper size where the pages having the printing paper size of the i-th lit of charge setting 35 are arranged in the lateral and longitudinal directions with their longitudinal directions set in the portrait orientation is large enough to cover the printing paper size designated in advance. When it is determined that the product of the number of pages Xp and the number of pages Yp is larger than 1, enlargement/reduction mode list-up program 104 determines that the printing paper size designated in advance is not covered, and proceeds the processing to S608. When it is determined that the product of the number of pages Xp and the number of pages Yp is equal to or smaller than 1, enlargement/reduction mode list-up program 104 determines that the printing paper size designated in advance is covered, and proceeds the processing to S613 because it does not have to be split and printed on multiple pages by using the poster print function and there is no need to be added into the enlargement/reduction mode list.

S608: When it is determined that the product of the number of pages Xp and the number of pages Yp is larger than 1, enlargement/reduction mode list-up program 104 determines whether or not a product of the number of pages Xq calculated at S605 and the number of pages Yq calculated at S606 is larger than 1 in order to determine whether or not the printing paper size where the pages having the printing paper size of the i-th list of charge setting 35 are arranged in the lateral and longitudinal directions with their longitudinal directions set in the landscape orientation is large enough to cover the printing paper size designated in advance. When it is determined that the product of the number of pages Xq and the number of pages Yq is larger than 1, enlargement/reduction mode list-up program 104 determines that the printing paper size designated in advance is not covered, and proceeds the processing to S609. When it is determined that the product of the number of pages Xq and the number of pages Yq is equal to or smaller than 1, enlargement/reduction mode list-up program 104 determines that the printing paper size designated in advance is covered, and proceeds the processing to S613 because it does not have to be split and printed on multiple pages by using the poster print function and there is no need to be added into the enlargement/reduction mode list.

S609: Enlargement/reduction mode list-up program 104, having determined that the product of the number of pages Xq and the number of pages Yq is larger than 1, compares the product of the number of pages Xp and the number of pages Yp with the product of the number of pages Xq and the number of pages Yq. This is for determining which of the portrait orientation and the landscape orientation the longitudinal direction of the printing page having the printing paper size of the i-th list of charge setting 35 should be set in to achieve more effective printing. Since a smaller product requires a smaller number of pages to be used, this is determined as effective.

When it is determined that the product of the number of pages Xp and the number of pages Yp is equal to or smaller than the product of the number of pages Xq and the number of pages Yq, enlargement/reduction mode list-up program 104 proceeds the proceeding to S610. When it is determined that the product of the number of pages Xp and the number of pages Yp is equal to or larger than the product of the number of pages Xq and the number of pages Yq, it proceeds the processing to S611.

S610: When it is determined that the product of the number of pages Xp and the number of pages Yp is equal to or smaller than the product of the number of pages Xq and the number of pages Yq, enlargement/reduction mode list-up program 104 adds a pattern in which the printing paper having the printing paper size of the i-th list of charge setting 35 is used with the longitudinal direction set in the portrait orientation into the enlargement/reduction mode list and proceeds to the processing at S612. At this time, enlargement/reduction mode list-up program 104 sets and adds “3” as enlargement/reduction mode ID of the enlargement/reduction mode list, the printing paper size of the i-th list of charge setting 35″ as the printing paper size, “a value obtained by multiplying a product of the number N of pages of the original document and the number of pages Xp by the number of pages Yp” as the number of printing pages, “the number of pages Xp” as X, “the number of pages Yp” as Y, and “portrait” as a paper orientation, and temporarily sets a provisional value of “0” for the number of color pages, the number of monochrome pages, the fee, and the minimum-fee flag.

S611: When it is determined that the product of the number of pages Xp and the number of pages Yp is larger than the product of the number of pages Xq and the number of pages Yq, enlargement/reduction mode list-up program 104 adds a pattern in which the printing paper having the printing paper size of the i-th list of charge setting 35 is used with the longitudinal direction set in the landscape orientation into the enlargement/reduction mode list and proceeds the processing to S612. At this time, enlargement/reduction mode list-up program 104 sets and adds “3” as enlargement/reduction mode ID of the enlargement/reduction mode list, the printing paper size of the i-th list of charge setting 35″ as the printing paper size, “a value obtained by multiplying a product of the number N of pages of the original document and the number of pages Xq by the number of pages Yq” as the number of printing pages, “the number of pages Xq” as X, “the number of pages Yq” as Y, and “landscape” as a paper orientation, and temporarily sets a provisional value of “0” for the number of color pages, the number of monochrome pages, the fee, and the minimum-fee flag.

S612: Next, enlargement/reduction mode list-up program 104 adds “1” to the number T of the lists.

S613: Enlargement/reduction mode list-up program 104 adds “1” to the loop counter i, which is then updated, in order to process the next items of charge setting 35. Then, the processing proceeds to S602.

Next, the processing of adding the reduction print mode using the N-up print function, which is performed by the enlargement/reduction list-up program, into the enlargement/reduction mode list is described by referring to FIGS. 1 and 2 according to steps expressed by S in the figures in the flow of the enlargement/reduction mode list creation processing in the first embodiment in FIG. 14. The process of adding the reduction print mode using the N-up print function into the enlargement/reduction mode list is processing performed at S407 in FIG. 11. The processing is processing of adding the reduction print mode using the N-up print function to print multiple pages on paper having a size larger than the designated size into the enlargement/reduction mode list by using charge setting 35. Charge setting 35 is a charge setting list as illustrated in FIG. 7, and enlargement/reduction mode list-up program 104 performs processing sequentially referring to the information of charge setting 35.

S701: Enlargement/reduction mode list-up program 104 initializes a loop counter i with “0.”

S702: Enlargement/reduction mode list-up program 104 determines whether or not the loop counter i has a value smaller than the total number I of items of the list of charge setting 35. When it is determined that the loop counter i has a value smaller than the total number I of items of the list of charge setting 35, it determines that all the items are not checked, and the processing proceeds to S703. When it is determined that the loop counter i has a value equal to or larger than the total number I of items of the list of charge setting 35, it determines that all the items have been checked, and thus the processing is terminated.

S703: Enlargement/reduction mode list-up program 104 calculates how many pages Xp of the printing paper having the printing paper size designated in advance can be arranged in the lateral direction in the printing paper having a printing paper size of the i-th list of charge setting 35, whose longitudinal direction is set in the landscape orientation, within a range without exceeding the width in the lateral direction. Here, the number of pages Xp arranged in the lateral direction can be obtained by dividing a width Wi of the printing paper size of the i-th list of charge setting 35 by a width Wo of the printing paper size designated in advance. Note that the number of paper sheets Xp is an integer which is obtained by rounding up after the decimal point.

S704: Enlargement/reduction mode list-up program 104 calculates how many pages Yp of the printing paper having the printing paper size designated in advance can be arranged in the longitudinal direction in the printing paper size of the i-th list of charge setting 35 is used in portrait orientation, whose longitudinal direction is set in the portrait orientation, within a range not exceeding the height in the longitudinal direction. Here, the number of pages Yp arranged in the longitudinal direction can be obtained by dividing a height Hi of the printing paper size of the i-th list of charge setting 35 by a height Ho of the printing paper size designated in advance. Note that the number of paper sheets Yp is an integer which is obtained by rounding up after the decimal point.

S705: Enlargement/reduction mode list-up program 104 calculates how many pages Xq of the printing paper having the printing paper size designated in advance can be arranged in the lateral direction in the printing paper having a printing paper size of the i-th list of charge setting 35, whose longitudinal direction is set in the landscape orientation, within a range not exceeding the width in the lateral direction. Here, the number of pages Xq arranged in the lateral direction can be obtained by dividing the height i of the printing paper size of the i-th list of charge setting 35 by the width Wo of the printing paper size designated in advance. Note that the number of pages Xq is an integer which is obtained by rounding up after the decimal point.

S706: Enlargement/reduction mode list-up program 104 calculates how many pages Yq of the printing paper having the printing paper size designated in advance can be arranged in the longitudinal direction in the printing paper having a printing paper size of the i-th list of charge setting 35, whose longitudinal direction is set in the landscape orientation, within a range not exceeding the height in the longitudinal direction. Here, the number of pages Yq arranged in the lateral direction can be obtained by dividing the width Wi of the printing paper size of the i-th list of charge setting 35 by the height Ho of the printing paper size designated in advance. Note that the number of paper sheets Yq is an integer which is obtained by rounding up after the decimal point.

S707: Enlargement/reduction mode list-up program 104 determines whether or not a product of the number of pages Xp calculated at S703 and the number of pages Yp calculated at S704 is larger than 1 in order to determine whether or not the printing paper having the printing paper size of the i-th list of charge setting 35 with the longitudinal direction set in the portrait orientation has a size covering the printing paper size designated in advance. When it is determined that the product of the number of pages Xp and the number of pages Yp is larger than 1, enlargement/reduction mode list-up program 104 determines that the N-up print is possible, and proceeds the proceeding to S709. When it is determined that the product of the number of pages Xp and the number of pages Yp is equal to or smaller than 1, it determines that the N-up print is impossible, and proceeds the processing to S708.

S708: Enlargement/reduction mode list-up program 104, having determined that the N-up print is impossible in the printing page having the printing paper size of the i-th list of charge setting 35 with the longitudinal direction set in the portrait orientation, determines whether or not a product of the number of pages Xq calculated at S705 and the number of pages Yq calculated at S706 is larger than 1 in order to determine whether or not the printing paper having the printing paper size of the i-th list of charge setting 35 with the longitudinal direction set in the landscape orientation has a size covering the printing paper size designated in advance.

When it is determined that the product of the number of pages Xq and the number of pages Yq is larger than 1, enlargement/reduction mode list-up program 104 determines that the N-up print is possible and proceeds the processing to S709. When it is determined that the product of the number of pages Xq and the number of pages Yq is equal to or smaller than 1, enlargement/reduction mode list-up program 104 determines that the N-up print is impossible, and proceeds the processing to S713 because printing on the printing paper having the printing paper size of the i-th list of charge setting 35 using the N-up print function is impossible and there is no need to be added into the enlargement/reduction mode list.

S709: At S707 or S708, enlargement/reduction mode list-up program 104, having determined that the N-up print is possible, compares a product of the number of pages Xp and the number of pages Yp with the product of the number of pages Xq and the number of pages Yq.

This is for determining which of the portrait orientation and the landscape orientation the longitudinal direction of the printing page having the printing paper size of the i-th list of charge setting 35 should be set in order to achieve more effective printing. Since a larger product indicates that a larger number of pages can be printed collectively on one printing medium, this is determined as effective. When it is determined that the product of the number of pages Xp and the number of pages Yp is larger than the product of the number of pages Xq and the number of pages Yq, enlargement/reduction mode list-up program 104 proceeds the proceeding to S710. When it is determined that the product of the number of pages Xp and the number of pages Yp is equal to or smaller than the product of the number of pages Xq and the number of pages Yq, it proceeds the processing to S711.

S710: When it is determined that the product of the number of pages Xp and the number of pages Yp is equal to or smaller than the product of the number of pages Xq and the number of pages Yq, enlargement/reduction mode list-up program 104 adds a pattern in which the printing paper having the printing paper size of the i-th list of charge setting 35 is used with the longitudinal direction set in the portrait orientation into the enlargement/reduction mode list and proceeds the processing at S712. At this time, enlargement/reduction mode list-up program 104 sets and adds “4” as enlargement/reduction mode ID of the enlargement/reduction mode list, the printing paper size of the i-th list of charge setting 35″ as the printing paper size, “a value obtained by dividing a quotient of the number N of pages of the original document by the number of pages Xp by the number of pages Yp” as the number of printing pages, “the number of pages Xp” as X, “the number of pages Yp” as Y, and “portrait” as a paper orientation, and temporarily sets a provisional value of “0” for the number of color pages, the number of monochrome pages, the fee, and the minimum-fee flag.

S711: When it is determined that the product of the number of pages Xp and the number of pages Yp is larger than the product of the number of pages Xq and the number of pages Yq, enlargement/reduction mode list-up program 104 adds a pattern in which the printing paper having the printing paper size of the i-th list of charge setting 35 is used with the longitudinal direction set in the landscape orientation into the enlargement/reduction mode list and proceeds the processing to S712. At this time, enlargement/reduction mode list-up program 104 sets and adds “4” as enlargement/reduction mode ID of the enlargement/reduction mode list, the printing paper size of the i-th list of charge setting 35″ as the printing paper size, “a value obtained by dividing a quotient of the number N of pages of the original document by the number of pages Xq by the number of pages Yq” as the number of printing pages, “the number of pages Xq” as X, “the number of pages Yq” as Y, and “landscape” as a paper orientation, and temporarily sets a provisional value of “0” for the number of color pages, the number of monochrome pages, the fee, and the minimum-fee flag.

S712: Enlargement/reduction mode list-up program 104 adds “1” into the number of lists T.

S713: Enlargement/reduction mode list-up program 104 adds “1” to the loop counter i, which is then updated, in order to process the next items of charge setting 35. Then, the processing proceeds to S702.

Next, fee calculation processing to be performed by the fee calculation program is briefly described by referring to FIGS. 1 and 2 according to steps expressed by S in the drawings of the flowchart illustrating the flow of the fee calculation processing in the first embodiment in FIG. 15. Note that this fee calculation processing is processing to be performed at S311 of FIG. 10. The processing is processing to calculate a fee on each item of the enlargement/reduction mode list listed up by enlargement/reduction mode list-up program 104. Fee calculation program 105 performs processing sequentially referring to the information of the enlargement/reduction list.

S801: Fee calculation program 105 initializes a loop counter r with “0.”

S802: Fee calculation program 105 determines that a fee is not calculated for all the items of the enlargement/reduction mode list when the loop counter r compares the number T of items of the enlargement/reduction mode list which are listed up by enlargement/reduction mode list-up program 104 with the loop counter r and when it is determined that a value of the loop counter r is smaller than the number T of items of the enlargement/reduction mode list. The processing then proceeds to S803. When it is determined that the value of the loop counter r is equal to or larger than the number T of items of the enlargement/reduction mode list, it determines that a fee is calculated for all the items of the enlargement/reduction mode list and proceeds the processing to S860.

S803: Fee calculation program 105 initializes the page counter i with “0” and initializes variable Pc storing the number of color pages and variable Pm storing the number of monochrome pages Pc for the items of the enlargement/reduction mode list for which the fee is calculated with “0.”

S804: Fee calculation program 105 determines a value of enlargement/reduction mode ID of the enlargement/reduction mode to be a calculation target. When the value of the enlargement/reduction mode ID is “1” or “2,” the processing at S810 is executed. When the value of the enlargement/reduction mode ID is “3,” the processing at S820 is executed. When the value of the enlargement/reduction mode ID is “4,” the processing at S840 is executed. Fee calculation program 105, having executed the processing at S810, S820, and S840, proceeds the processing to S802 and forms a loop. Note that the processing at S810, S820, and S840 is described later in detail.

S860: Fee calculation program 105 leaves the lower fee and deletes the higher fee from the enlargement/reduction mode list when the enlargement/reduction mode IDs are the same and the numbers of pages are the same. This is because a more effective option for each enlargement/reduction mode is provided for user P, and the option with a lower efficiency is deleted from the enlargement/reduction mode list.

S861: Fee calculation program 105 extracts a lowest fee from the items in the enlargement/reduction mode list and changes the minimum-fee flag of the item of the enlargement/reduction mode list to “1”. Then, the processing is terminated. In this manner, fee calculation program 105 completes the enlargement/reduction mode list and enlargement/reduction display program 106 displays the enlargement/reduction mode setting screen on display 13 based on the completed enlargement/reduction mode list.

Next, fee calculation processing to be performed by the fee calculation program when the enlargement/reduction mode ID is “1” or “2” is described by referring to FIGS. 1 and 2 according to steps expressed by S in the drawings of the flowchart illustrating the flow of the fee calculation processing in the first embodiment in FIG. 16. Note that this fee calculation processing is performed at S810 of FIG. 15.

S811: Fee calculation program 105 compares the page counter i with the total number N of pages. When it is determined that the page counter i is smaller than the total number N of pages, this means that all the pages are not processed. Then, the processing proceeds to S812. When it is determined that the page counter i is equal to or larger than the total number N of pages, this means that all the pages are processed. Then, the processing proceeds to S816.

S812: Fee calculation program 105 determines whether or not the data of the i-th page is a color page. When it is determined that the data is a color page, the processing proceeds to S813. When it is determined that it is not a color page, i.e., a monochrome page, the processing proceeds to S814.

Here, the determination of color page is performed using a RGB (Red Green Blue) value which is color information designated for each data in the page data. Color information whose values of a R element, a G element, and a B element of the RGB value are equal to one another is dealt as monochrome information. Color information in which any of a R element, a G element, and a B element of the RGB value has a different value and is dealt with as color information. Fee calculation program 105 performs this determination processing for all the data in the page, and determines that a page having the color information is a color page and a page having only the monochrome information is a monochrome page.

S813: Fee calculation program 105 having been determined as the color page at S812 adds “1” to variable Pc storing the number of color pages and proceeds the processing to S815.

S814: On the other hand, fee calculation program 105 having been determined as the monochrome page at S812 adds “1” to variable Pm storing the number of monochrome pages and proceeds the processing to S815.

S815: Fee calculation program 105 adds “1” to the page counter i, and proceeds the processing to S811 to perform the processing on the next page.

S816: Fee calculation program 105, having determined that the page counter i is equal to or larger than the total number N of pages and having determined that all the pages are processed at S811, substitutes the value of variable Pc for the number of color pages of the r-th item of the enlargement/reduction mode list and substitutes the value of variable Pm for the number of monochrome pages. Furthermore, fee calculation program 105 adds the product of variable Pc and the color unit price to the product of variable Pm and the monochrome unit price, and substitutes the added value for fee Pr. Note that r is a loop counter. Here, the color unit price and the monochrome unit price are acquired by searching the charge setting list illustrated in FIG. 7 of charge setting 35 based on the determined printing paper size.

S817: Fee calculation program 105 adds “1” to the loop counter r in order to process the next items of enlargement/reduction mode list. Then, the processing is terminated.

Next, fee calculation processing to be performed by the fee calculation program when the enlargement/reduction mode ID is “3” is described by referring to FIGS. 1 and 2 according to steps expressed by S in the drawings of the flowchart illustrating the flow of the fee calculation processing in the first embodiment in FIG. 17. Note that this fee calculation processing is performed at S820 of FIG. 15.

S821: Fee calculation program 105 calculates the number I3 of pages in which one page is split in such a manner that Xr, which is X of the r-th item of the enlargement/reduction mode list, is multiplied by Yr, which is Y of the r-th item of the enlargement/reduction mode list.

S822: Fee calculation program 105 compares the page counter i with the total number N of pages. When it is determined that the page counter i is smaller than the total number N of pages, this means that all the pages are not processed. Then, the processing proceeds to S823. When it is determined that the page counter i is equal to or larger than the total number N of pages, this means that all the pages are processed. Then, the processing proceeds to S830.

S823: Fee calculation program 105 initializes counter i3 for sequentially processing page number I₃ in which one page is split to “0.”

S824: Fee calculation program 105 compares the page counter i₃ with the number I₃ of split pages. When it is determined that the page counter i₃ is smaller than the number I₃ of split pages, this means that all the pages to be split for one document page are not processed. Then, the processing proceeds to S825. When it is determined that the page counter i₃ is equal to or larger than the number I₃ of split pages, this means that all the pages to be split for one document page are processed. Then, the processing proceeds to S829.

S825: Fee calculation program 105 determines whether or not the data of the i-th page is a color page. When it is determine that the data is a color page, the processing proceeds to S826. When it is determined that it is not a color page, i.e., a monochrome page, the processing proceeds to S827.

Here, process of determining whether it is the color page or the monochrome page is the same processing as that at S812 of FIG. 16. However, when the poster print function is used, the page is split. Accordingly, the determination is entirely performed on all the split regions. Fee calculation program 105 places the page data in the center of the size in which the paper having the r-th printing paper size of the enlargement/reduction mode list is arranged with X pages in the lateral direction and Y pages in the longitudinal direction, and checks whether the drawing data in the region of each paper size is color information or monochrome information.

S826: Fee calculation program 105, having been determined as the color page at S825, adds “1” to variable Pc storing the number of color pages and proceeds the processing to S828.

S827: On the other hand, fee calculation program 105, having been determined as the monochrome page at S825, adds “1” to variable Pm storing the number of monochrome pages and proceeds the processing to S828.

S828: Fee calculation program 105 adds “1” to the page counter i₃, and proceeds the processing to S824 to perform the processing on the next page in the poster print function.

S829: Fee calculation program 105, having determined that counter i₃ has a value equal to or larger than the number I₃ of split pages at S824, adds “1” to page counter i and proceeds the processing to S822 to process the next page.

S830: Fee calculation program 105, having determined that the page counter i is equal to or larger than the total number N of pages and having determined that all the pages are processed at S822, substitutes the value of variable Pc for the number of color pages of the r-th item of the enlargement/reduction mode list and substitutes the value of variable Pm for the number of monochrome pages. Furthermore, fee calculation program 105 adds the product of variable Pc and the color unit price to the product of variable Pm and the monochrome unit price and substitutes the added value for the fee Pr. Note that r is a loop counter. Here, the color unit price and the monochrome unit price are acquired by searching the charge setting list illustrated in FIG. 7 of charge setting 35 based on the determined printing paper size.

S831: Fee calculation program 105 adds “1” to the loop counter r in order to process the next items of enlargement/reduction mode list. Then, the processing is terminated.

Next, fee calculation processing to be performed by the fee calculation program when the enlargement/reduction mode ID is “4” is described by referring to FIGS. 1 and 2 according to steps expressed by S in the drawings of the flowchart illustrating the flow of the fee calculation processing in the first embodiment in FIG. 18. This fee calculation processing is performed at S840 of FIG. 15.

S841: Fee calculation program 105 calculates the number I₄ of pages to be compiled on one page in such a manner that Xr, which is X of the r-th item of the enlargement/reduction mode list, is multiplied by Yr, which is Y of the r-th item of the enlargement/reduction mode list.

S842: Fee calculation program 105 compares the page counter i with the total number N of pages. When it is determined that the page counter i is smaller than the total number N of pages, this means that all the pages are not processed. Then, the processing proceeds to S843. When it is determined that the page counter i is equal to or larger than the total number N of pages, this means that all the pages are processed. Then, the processing proceeds to S853.

S843: Fee calculation program 105 initializes counter i₄ for sequentially processing number I₄ of pages to be put together on one page and flag F indicating the color page to “0.”

S844: Fee calculation program 105 compares the page counter i₄ with the number I₄ of compiled pages. When it is determined that the page counter i₄ is smaller than the number I₄ of compiled pages, this means that all the pages to be compiled for the printing paper size are not processed yet. Then, the processing proceeds to S845. When it is determined that the page counter i₄ is equal to or larger than the number I₄ of compiled pages, this means that all the pages to be compiled for the printing paper size are processed. Then, the processing proceeds to S849.

S845: Fee calculation program 105 determines whether or not the data of the i-th page is a color page. When it is determine that the data is a color page, the processing proceeds to S846. When it is determined that it is not a color page, i.e., a monochrome page, the processing proceeds to S847.

Here, the process of determining whether it is the color page or the monochrome page is the same processing as that at S812 of FIG. 16. However, when the N-up function is used, the pages are compiled. Accordingly, the determination is entirely performed on all the pages to be compiled. Accordingly, fee calculation program 105 checks whether each logic page to be compiled is color or monochrome.

S846: Fee calculation program 105, having determined that the page is a color page at S845, substitutes “1” for flag F.

S847: Fee calculation program 105 adds “1” to counter i₄.

S848: Fee calculation program 105 compares the value in which page counter i is added to counter i₄ with the value of the total number N of pages. When it is determined that the value in which page counter i is added to counter i₄ is smaller than the total number N of pages, this means that an unprocessed page exists. Thus, the processing proceeds to S844. When it is determined that the value in which counter i is added to counter i₄ is equal to or larger than the total number N of pages, this means that all the pages are processed. Thus, the processing proceeds to S849.

S849: Fee calculation program 105 determines whether or not flag F indicating that the entire page in which the multiple pages are compiled is a color page is “1.” When it is determined that flag F is “1,” the processing proceeds to S850, while when it is determined that flag F is no “1,” the processing proceeds to S851.

S850: Fee calculation program 105, having determined that flag F is “1,” i.e., the entire page in which multiple pages are compiled is a color page, adds “1” to variable Pc storing the number of color pages and proceeds the processing to S852.

S851: On the other hand, fee calculation program 105, having determined in S849 that flag F is not “1,” i.e., the entire page in which multiple pages are compiled is a monochrome page, adds “1” to variable Pm storing the number of monochrome pages and proceeds the processing to S852.

S852: Fee calculation program 105 adds counter I₄ to the page counter i, and proceeds the processing to S842.

S853: Fee calculation program 105, having determined that the page counter i is equal to or larger than the total number N of pages and having determined that all the pages are processed at S842, substitutes the value of variable Pc for the number of color pages of the r-th item of the enlargement/reduction mode list and substitutes the value of variable Pm for the number of monochrome pages. Furthermore, fee calculation program 105 adds the product of variable Pc and the color unit price to the product of variable Pm and the monochrome unit price and substitutes the value for the fee Pr. Note that r is a loop counter. Here, the color unit price and the monochrome unit price are acquired by searching the charge setting list illustrated in FIG. 7 of charge setting 35 based on the determined printing paper size.

S854: Fee calculation program 105 adds “1” to the loop counter r in order to process the next items of the enlargement/reduction mode list. Then, the processing is terminated. As described above, in the first embodiment, when enlargement or reduction printing is designated, multiple different print modes for obtaining a print result with the same enlargement/reduction rate are displayed on a display together with a fee thereof to inform a user so that the user can select a print mode. Accordingly, such effect can be obtained that the user can select an optimum enlargement/reduction print mode by considering the fee among the provided multiple print modes.

Page data creation program 220 as a print data creation unit is a print data creation program to create print data based on the output mode selected by enlargement/reduction mode display program 219, and creates page data from the image data of the document read by image scanner 204 as print data based on copy setting 213 and the enlargement/reduction mode selected by enlargement/reduction mode display program 219.

Effects of the above-described configuration are described.

Firstly, print (copy) processing to be performed by the copier as the image processing system is briefly described by referring to FIG. 23 according to steps expressed by S in the drawing of the flowchart illustrating the flow of the printing processing in the second embodiment in FIG. 24.

S1101: User P places a target document to be copied on image scanner 204 of copier 200.

Setting change program 215 in copier 200 displays currently-set contents on display 203 and performs print setting change processing to change copy setting 213 in storage 212 based on the print setting information inputted in input unit 201 through the operation of user P. Copy setting 213 is referred when the image data of the document is converted into print data.

S1102: Controller 202 accepts the operation of user P instructing copy through input unit 201 and starts copying.

S1103: Controller 202 performs page image scan processing to read an image depicted on the placed document by image scanner 204.

S1104: Controller 202 performs print data creation processing of the page image read by image scanner 204 to process and print the page image.

S1105: Printer 205 prints the created print data of the page image. At this time, print unit 205 performs printing after feeding the designated printing medium from paper storage 206 and the charges based on charge setting 214 stored in storage 212, and then the processing is terminated.

Next, print setting change processing to be performed by the setting change program of the copier is described by referring to FIG. 23 according to steps expressed by S in the drawing of the flowchart illustrating the flow of the print setting change processing in the second embodiment in FIG. 25. Note that this print setting change processing is performed at S1101 of FIG. 24.

S1201: Setting change program 215 acquires copy setting 213 including a document paper size, a printing paper size, and an enlargement/reduction rate from storage 212.

S1202: Setting change program 215 sets the acquired print setting as setting parameters for each item. For example, setting change program 215 sets “A4” as the setting parameter of the document paper size, and also sets “A4” as the setting parameter of the printing paper size, and sets “100%” as the setting parameter of the enlargement/reduction rate.

S1203: Setting change program 215 displays a GUI in which the setting parameter set at S1202 is reflected on display 13.

S1204: Setting change program 215 accepts the operation of changing the settings of the respective items, which is made by user P through input unit 201, and changes the settings of the items. For example, when the print data illustrated in FIG. 3 is copied, the document size is “A4” and thus setting change program 215 keeps the setting parameter of the document paper size at “A4.” Then, since the enlargement/reduction rate is 141%, setting change program 215 changes the setting parameter of the printing paper size from “A4” to “A3,” and the enlargement/reduction rate from “100%” to “141%.”

S1205: Setting change program 215 saves the changed setting in copy setting 213.

S1206: Setting change program 215 displays termination of the print setting on the GUI. When it is determined that an “OK” button is pressed down in the GUI, the processing is terminated. When it is determined that a “Cancel” button other than the “OK” button is pressed down, the processing proceeds to S1204 and repeats the processing S1204 and 1205.

Next, print data creation processing to be performed by the copier is briefly described by referring to FIG. 23 according to steps expressed by S in the drawing of the flowchart illustrating the flow of the print data creation processing in the second embodiment in FIG. 26. Note that this print setting change processing is processing to be performed at S1104 of FIG. 24.

S1301: Charge setting acquisition program 216 acquires the document paper size, paper size names, widths, and heights of the printing paper size, and enlargement/reduction rates R (%) from copy setting 213.

S1302: Charge setting acquisition program 216 determines whether or not the acquired enlargement/reduction rate R is 100%. When it is determined that it is 100%, the enlargement/reduction is not performed, and thus the processing proceeds to S1313 to create page data having the designated setting. When it is determined that it is not 100%, the processing proceeds to S1303.

S1303: When it is determined that the acquired enlargement/reduction rate R is not 100%, fee acquisition program 216 acquires charge setting 214.

S1304: Charge setting acquisition program 216 acquires I which is the number of items of charge setting 214. As illustrated in FIG. 7, charge setting 214 is configured of paper sizes which are stored in trays A41 to E45 of paper storage 206 as paper storage trays, a color unit price as a color print unit price when color printing is made on each paper size, and a monochrome print unit price when monochrome printing is made on each paper size. Thus, the number I of the items can be acquired from the configuration. In the example illustrated in FIG. 7, the number I of the items is 5.

S1305: Charge setting acquisition program 216 checks a scan state of the target document to be copied. Here, the image data which is obtained by scanning each page of the document is delivered to page data creation program 220 after scanning all the pages to be copied without being delivered to page data creation program 220 to be processed. During this time, the image data which is obtained by scanning the document is stored in storage 212.

S1306: Charge setting acquisition program 216 proceeds the processing to S1305 until all the pages of the document are scanned. When the scanning is terminated, the processing proceeds to S1307. Note that the end of the scanning can be detected by a change in the state of the automatic document feeder of image scanner 204 from a state where paper is present to a state where paper is absent.

S1307: Charge setting acquisition program 216, detecting the end of the scanning, acquires the total number N of pages of the print data to be copied from the scanned print data.

S1308: Next, enlargement/reduction mode list-up program 217 creates an enlargement/reduction mode list. Note that the processing of creating the enlargement/reduction mode list is similar to the processing of FIGS. 11 to 14 in the first embodiment, and the description thereof is omitted.

S1309: Next, fee calculation program 218 calculates a fee for each item of the created enlargement/reduction mode list. Note that the processing of calculating the fee for each item of the enlargement/reduction mode list is same as the processing of FIGS. 15 to 18 in the first embodiment, except for the method of determining whether it is color or monochrome, and the description thereof is omitted. In the method of determining color or monochrome in the embodiment, when variations of the color information of all the image data are within a range of threshold for each of the RGB elements, it is determined as monochrome while when variations thereof are outside the threshold, it is determined as color.

Here, the variations mean differences among the RGB elements. For example, in the case of RGB (0, 0, 0) and RGB (128, 128, 128), the variation become “0” and in the case of RGB (126, 128, 130), the variation becomes “4.”

S1310: Next, enlargement/reduction mode display program 219 displays the enlargement/reduction mode setting screen. Note that the enlargement/reduction mode setting screen is the same as that of the first embodiment.

S1311: Enlargement/reduction display program 219 accepts a selection operation of a desired enlargement/reduction mode by user P on the enlargement/reduction mode setting screen.

S1312: Enlargement/reduction mode display program 219 accepts an operation of terminating the enlargement/reduction mode setting screen by user P on the enlargement/reduction mode setting screen. When OK button 123 illustrated in FIG. 4 is pressed down, the selected enlargement/reduction mode is adopted for the page data creation processing. When cancel button 124 is pressed down, the selected enlargement/reduction mode is not adopted for the page data creation processing but the enlargement/reduction mode designated in advance is adopted for the page data creation processing. At that time, enlargement/reduction mode display program 219 starts supplying the image data stored in storage 212 with page data creation program 220.

S1313: Page data creation program 220 adopts the selected or designated enlargement/reduction mode to create page data. Then, the processing is terminated.

As described above, in the second embodiment, in the copier, when enlargement or reduction copy is designated, multiple different print modes for obtaining a print result with the same enlargement/reduction rate are displayed on a display together with a fee thereof to inform a user so that the user can select a print mode. Accordingly, such effect can be obtained that the user can select an optimum enlargement/reduction print mode by considering the fee among the provided multiple print modes.
